过程 26.1. autoconf and automake step by step

1. create directory

   % mkdir devel
   % cd devel
   % mkdir hello
   % cd hello
   					

   create a file

   vim hello.c
   
   　　#include
   　　int main(int argc, char** argv)
   　　{
   　　printf(``Hello, GNU!\n'');
   　　return 0;
   　　}
   					

2. autoscan

   neo@debian:~/workspace/devel/hello$ autoscan
   neo@debian:~/workspace/devel/hello$ ls
   autoscan.log  configure.scan  hello.c
   					

3. configure.in

   cp configure.scan configure.in
   
   neo@debian:~/workspace/devel/hello$ aclocal
   neo@debian:~/workspace/devel/hello$ autoconf
   neo@debian:~/workspace/devel/hello$ ls
   autom4te.cache  autoscan.log  configure  configure.in  configure.scan  hello.c
   					

4. Makefile.am

   neo@debian:~/workspace/devel/hello$ vim Makefile.am
   neo@debian:~/workspace/devel/hello$ cat Makefile.am
   AUTOMAKE_OPTIONS= foreign
   bin_PROGRAMS= hello
   hello_SOURCES= hello.c
   neo@debian:~/workspace/devel/hello$
   					

   $ automake --add-missing
   configure.in: no proper invocation of AM_INIT_AUTOMAKE was found.
   configure.in: You should verify that configure.in invokes AM_INIT_AUTOMAKE,
   configure.in: that aclocal.m4 is present in the top-level directory,
   configure.in: and that aclocal.m4 was recently regenerated (using aclocal).
   automake: no `Makefile.am' found for any configure output
   automake: Did you forget AC_CONFIG_FILES([Makefile]) in configure.in?
